Leisure has often been defined as a quality of experience or as free time. Free time is time spent away from business, work, job hunting, domestic chores, and education, as well as necessary activities such as eating and sleeping. Situationist International proposes that leisure does not evolve from free time, and free-time is an illusory concept that is rarely fully "free"; economic and social forces appropriate free time from the individual and sell it back to them as the commodity known as "leisure". Certainly most people's leisure activities are not a completely free choice and may be constrained by social pressures, e.g. people may be coerced into spending time gardening by the need to keep up with the standard of neighbouring gardens or go to a party because of social pressures.

A hobby is a regular activity done for enjoyment, typically during one's leisure time, not professionally and not for pay. Hobbies include collecting themed items and objects, engaging in creative and artistic pursuits, playing sports, or pursuing other amusements. Participation in hobbies encourages acquiring substantial skills and knowledge in that area. A list of hobbies changes with renewed interests and developing fashions, making it diverse and lengthy. Hobbies tend to follow trends in society, for example stamp collecting was popular during the nineteenth and twentieth centuries as postal systems were the main means of communication, while video games are more popular nowadays following technological advances.

A toy is an item that is used in play, especially one designed for such use. Playing with toys can be an enjoyable means of training young children for life in society. Different materials like wood, clay, paper, and plastic are used to make toys. Many items are designed to serve as toys, but goods produced for other purposes can also be used. For instance, a small child may fold an ordinary piece of paper into an airplane shape and "fly it".
